Its hard to remember a time before the advent of drag-and-drop application development. In many Java tools, however, a facade of component assembly has done a poor job of concealing the reality of cumbersome and easily corrupted code behind the scenes.

That gap is closing in a more convincing and coherent fashion with the arrival this spring of Sun Microsystems Inc.s JavaServer Faces technology. Comprising classes that represent components, along with facilities for rendering those components and handling their events, JavaServer Faces will soon come to market in the convenient form of Suns Java Studio Creator application development environment.

However, the beta code we tested did these things at a leisurely pace on anything less than a multigigahertz processor with at least a half-gigabyte of RAM.

eWEEK Labs found the Java Studio Creator environment to be competitive with other drag-and-drop rivals, including Borland Software Corp.s JBuilder X Developer for Java and Microsoft Corp.s Visual Studio .Net 2003 for the various .Net languages.

During tests, Creator paced the state of the art in synchronizing multiple views of work in progress. For example, when we made a pop-up menu choice that enabled a user-interface behavior, the environment immediately displayed the associated code on a nearby property sheet.

We also were able to build database queries in a visual navigator window while previewing resulting changes to corresponding SQL commands. Various UI options, such as representing a table entry by a command button, were readily chosen from dialog boxes rather than requiring tedious construction and coding.

At some point, actual business logic will require writing some Java code, and the Java Studio Creator environment includes a source code editor with pop-up error tips and responsive code-browsing aids. Cross-referencing between the visual UI builder and the lower-level Java methods of GUI control behaviors was convenient and obvious.

The price of this generous behind-the-scenes support is a demand for equally generous hardware. Beta code or not, a laptop with 256MB of RAM should not need 23 minutes to make an initial deployment of a simple application or more than 3 minutes to make a simple change to a window title and rerun the application.

Developers should invest in adequate memory—good advice for any modern tools, as half-gigabyte appetites become more common. Were also confident that Sun will invest some effort in optimization before Java Studio Creator faces paying customers.
